All three Balancing Gadgets feature an internal low-noise linear power supply, direct coupled transformerless analog circuitry and our exclusive input design that suppresses common mode noise. The result is the most sonically-transparent devices available. Never any buzz, hum, hiss or RFI — just pure, clean sound, even with long unbalanced cables or a ground loop between the gadget and the source.
Stereo Balancing Gadget
Converts unbalanced stereo -10dBv audio via two RCA/Phono jacks into professional +4dBu fully balanced lines on two XLR connectors. Ideal for a single playback-only consumer device. State-of-the-art analog circuitry is low-distortion, low-noise, and includes DC offset correction and our exclusive input stage that reduces ground-loop noise.
Dual Stereo Balancing Gadget
We stuffed two Stereo Balancing Gadgets into a single box. Two playback-only consumer devices feed four RCA/Phono jacks at -10dBv. 4 XLR connectors deliver +4dBu balanced audio to your professional equipment. Output amplifiers capable of driving +26dBu into long cables, even low-impedance 600Ω loads.
Bidirectional Balancing Gadget
Converts one stereo pair from unbalanced to balanced and another stereo pair from balanced to unbalanced. Perfect for a recording device or a computer sound-card. All unbalanced and balanced signals are on RCA/Phono jacks and XLR connectors, respectively. Plenty of gain in the unlocked position means even low-level computer sound-cards are no problem.
